Introduction

Police effectiveness refers to the extent to which policing achieves its proper, officially sanctioned goals. Consideration of police effectiveness turns out to be quite complicated for several reasons, including (1) the police have multiple goals, making their bottom line multidimensional; (2) the relative priority of police goals is subject to discussion and debate among the public and within the police field; and (3) assessing police effectiveness is methodologically challenging. Fortunately, these issues have gotten substantial attention in the police field since about the mid-20th century, and many effectiveness-oriented studies have been undertaken. These studies can be organized according to police practices (strategies, tactics, and programs) and desired effects (such as reducing crime, solving crime, and enhancing police legitimacy). Because researchers and police officials have made police effectiveness a top priority, we know much more about “what works” in policing than we did in 1970.

General Overviews

As studies of police effectiveness began accumulating in the 1970s, so did efforts to summarize and synthesize findings. Kelling 1978 is an early review from one of the key researchers involved in the pioneering Police Foundation studies of the 1970s, including the Kansas City Preventive Patrol Experiment. Sherman 1986 makes the important observation that communities vary, and thus what works (i.e., what is effective) might vary depending on community characteristics. Cordner and Hale 1992 is an edited collection of essays on various “what works” topics in policing, while Bayley 1998 provides reports from nine effectiveness-oriented studies. Sherman 1997 and Weisburd and Eck 2004 provide updated reviews of police effectiveness studies across a range of independent and dependent variables. The most exhaustive and systematic review is Skogan and Frydl 2004. Equally wide-ranging is the collection of point–counterpoint essays on such topics as community policing, “broken windows” policing, hot spots policing, and Compstat in Weisburd and Braga 2006. Neyroud 2009 provides a perspective on police effectiveness and policing developments in the United Kingdom.

    E-mail Citation »

    Early review of evidence about what works in policing. Makes the case that communities differ in various ways and therefore the effectiveness of police practices also varies. Calls for more careful studies in different types of communities.

    E-mail Citation »

    Chapter on policing in a larger compendium assessing what works in preventing crime. Early example of meta-analysis to assess and aggregate findings from diverse studies. Identifies four police practices that work, five that do not work, and seven that are promising. Mainly focuses on just one of the goals of policing (reducing crime).

    Encyclopedic review of police effectiveness research. The report concludes that focused and tailored police strategies are most effective in controlling crime and disorder. Also the report found virtually no scientific research on many aspects of police effectiveness, even though police have become quite open to research and evaluation.

    Widely cited review by two leading police researchers. They conclude that policing focused on hot spots is most effective at reducing crime and disorder. Diffuse models of community policing reduce fear, while problem-oriented policing shows promise in reducing crime, disorder, and fear. Available onlinefor purchase or by subscription.
